The water molecule is amphoteric in aqueous solution. It can either gain a proton to form a hydronium ion H 3 O +, or else lose a proton to form a hydroxide ion OH −. [7] Another possibility is the molecular autoionization reaction between two water molecules, in which one water molecule acts as an acid and another as a base. H 2 O + H 2 O ...
The self-ionization of water (also autoionization of water, autoprotolysis of water, autodissociation of water, or simply dissociation of water) is an ionization reaction in pure water or in an aqueous solution, in which a water molecule, H 2 O, deprotonates (loses the nucleus of one of its hydrogen atoms) to become a hydroxide ion, OH −.
In chemistry, an amphiphile (from Greek αμφις (amphis) ' both ' and φιλíα ' love, friendship '), or amphipath, is a chemical compound possessing both hydrophilic (water-loving, polar) and lipophilic (fat-loving, nonpolar) properties. [1] Such a compound is called amphiphilic or amphipathic.
Ion exchange is a method widely used in household filters to produce soft water for the benefit of laundry detergents, soaps, and water heaters. This is accomplished by exchanging divalent cations (such as calcium Ca 2+ and magnesium Mg 2+ ) with highly soluble monovalent cations (e.g., Na + or H + ) (see water softening ).
Microplastics were detected in almost every seafood sample found off the coast of the western U.S. in a recent study. The particles were found in the edible tissue of six different species of fish.
Compared with the European Union, for example, U.S. adults are drinking an average of 57.5 ounces of water per day, while British adults are drinking an average of 33.8 ounces per day, according ...
Soaking in hot water can improve blood circulation and reduce stress and anxiety. Any tub will do, but ambiance and scented candles are encouraged. 10. Challenge yourself with a crossword puzzle ...
In some cases, both hydrophilic and hydrophobic properties occur in a single molecule. An example of these amphiphilic molecules is the lipids that comprise the cell membrane. Another example is soap, which has a hydrophilic head and a hydrophobic tail, allowing it to dissolve in both water and oil.
